The calculation for reg_packet_size in gdb_get_registers_packet() could
generate a wrong result in the case of multiple registers whose size is
not a multiple of 8.
The current calculation sums the sizes for all registers then rounds the result
up to the next multiple of 8.
Instead it should round each register size up individually and sum the results for all registers.

gdb connect can fail when the flash has not been probed.
During gdb connect, the flash layout is reported, but this
can not be automatically detected for a target that is
powered up and OpenOCD supports connecting to gdb server
even if the target is powered down.
The solution is to turn of the gdb_memory_map feature.

This addresses what would otherwise be something of a functional
regression. An earlier version of the interface had a dangerous
problem: it would silently erase data outside the range it was
told to erase. Fixing that bug turned up some folk who relied on
that unsafe behavior. (The classic problem with interface bugs!)
Now they can get that behavior again. If they really need it,
just specify "pad".

The gdb_port command can be invoked during normal execution
to report the port used for gdb, whereas it was listed as
CONFIG stage only, which caused an error when excuting
it to return the reported error.
Also in line with the grander goal of making more commands
available during all "modes" (perhaps retiring config mode),
there is no particular reason to limit gdb_port to the
config stage.

Most commands are usable only at runtime; so don't bother saying
that, it's noise. Moreover, tokens like EXEC are cryptic. Be
more clear: highlight only the commands which may (also) be used
during the config stage, thus matching the docs more closely.
There are
- Configuration commands (per documentation)
- And also some commands that valid at *any* time.
Update the docs to note that "help" now shows this mode info.
This also highlighted a few mistakes in command configuration,
mostly commands listed as "valid at any time" which shouldn't
have been. This just fixes ones I noted when sanity testing.

It's less accepting of signed char ... insisting that e.g. tolower()

It's probably good to phase out such usage, given the number of bugs

Rework gdb_init to create flexible APIs (gdb_target_add_{one,all}) and
static helper (gdb_target_start) for starting GDB services. Eliminates
duplicated code and provides general mechanisms for adding GDB services.
The 'init' command is updated to call the new API, and later patches can
decouple its policy of adding all targets therein.
Provides the new capability to use both piped and TCP servers when
multiple targets are defined. The first target fills the pipe, and
others will be started on TCP ports (unless disabled, i.e. gdb_port=0).
Several of the sites now using target_type_name() really
ought to be using an instance-specific name. Create a
function called target_name(), accessing the instance's
own (command) name.
Use it in several places that really should be displaying
instance-specific names. Also in several places which
were already doing so, but which had no wrapper to call.

There are two names that may matter on a per-target basis.
One is a per-instance name (for example, "at91sam7s.cpu").
The other is the name of its type (for example, "arm7tdmi"),
which is shared among multiple targets.
Currently target_get_name() returns the type name, which is
misleading and is rarely appropriate for target diagnostics.
Rename that as target_type_name().
